- OIL-BURNING STOCK-TANK HEATER.

Application filed April 16, 1924. Serial No; 706,934;

An object of this inventioniis to provide an improved construction foroil-burning stocktank heaters.

A further object of this invention is; toprovide an improvedconstruction of means for supplying air to a stock-tankheater.[

A further object of: this invention is to provide improved meansforsupportingz a fuel tank and distributing the contents thereof to aburner.

A further object of this-invention isitopro vide' an improvedconstruction for a radiatorin a' stoclctank beaten: 1

invention consists in the"construct-ion arrangement, and combination ofelements, hereinafter set forth, pointed out in the claims andillustrated by theaccompanying drawing", in whiclr- I Figure 1 is a sideelevation, partly in sec tion, of the complete; device. Figure 2 is aplan view of the device shown in Figure 1, dotted lines indicatinginterior parts.

In the construction of the device as shown the numeral 1 designates aburner chamber which may be made of separate plates con nected andsealed together. The burner chamber 1 preferably is prismatic in formand of a height substantially double its width and is adapted to bemounted in a stock-tank and 0 partially submerged therein. An oil-burner8 is removably and replaceably mounted within and rests on the bottom ofthe chamber 1 and the major portion of the bottom'of said burnerpreferably is spaced from the bottom of the chamber to avoid excessivecooling of the burner on account of the proximity of cold watersurrounding said chamber. The burner Sis formed with an upwardly-openingcavity, having a ridgedor serrated bottom adapted to contain liquidfuel, such as kerosene or distillate. An air conduit 4 is mounted in thechamber 1 and the body thereof may be formed open on one side toward anadjacent wall of the chamber and formed with flanges 4! adapted to bebolted to said wall. The conduit 4 extends above and laterally acrossthe adjacent wall of the chamber 1 and is provided with adownwardly-opening mouth 5 outside said Wall. The lower end portion ofthe conduit 4 is extended laterally and downwardly on curves toward, andterminates with an open end slightly above the burner 3. A fuel tank 6is mounted on and fixed to the upper end portion of the conduit 5 l anda fuel pipe 7, controlled by a needlevalve 8, leads from said tankthrough the 1nwardly-extending end portion of the conduit, 4 and.terminates with an open lower end axially of. the lower open end of theconduit and of the burner 3. The fuelpipe 7 extends, in part,verticallythrough thecentra-l portion of the chamber 1, and a cover 11 is formedof two parts slidingly mounted in opposite.

directions of said pipe and adapted to close the upper. end of saidchamber; A. window 9, preferably made ofmica, is mounted in one partofthe cover'll. A chamber Qpreferably constructedof metal by molding,substantially circular in cross-sectiomis formed with a flange 2 adaptedto be bolted to one wall: of the chamber 1, said chamber 2 being formedwith an open end communicating with hole 1 1111 said wall of the chamber1.' The chamber Qalsoisformed with a foot2 adaptedlto rest on the floorof a tank. The endlportion of the chamber 2 adjacent the chamber 1- isoblique in order that when the chambers are connected the bottom of thechamber 2 will be inclined toward the chamber 1. Thus provision is madefor draining condensation from the chamber 2 into the chamber 1 and alsofor upward draft through the hole 1'. The chamber 2 is taperedthroughout its length and is recurved substantially at its center, theupper portion of the chamber trending at an acute angle to the lowerportion thereof and terminating in a circular Vertical upper end adaptedto receive a flue 10.

The chamber 2 has its upper end substantially flush with the top of thechamber 1 and above the level of the water in the tank, and the flue 10may extend any desired distance upwardly {)0 give draft for oilcombustion in said cham- In'praotical use, a quantity of liquid fuel isdeposited through the pipe 7 on the burner 3. The liquid fuel on theburner may be ignited by means introduced through the top of the chamber1 when one or the other part 11 of the cover is moved outwardly. A funther and continuous supply of liquid fuel is led to the burner 3 throughthe pipe 7 and is regulated and controlled by manual adj ustment of theneedle valve 8. A supply of atmospheric air to maintain combustion onthe burner 3 is provided through the conduit 4 and the entrance to saidconduitopens clown- 'wardly to guard'against the introduction of rain,sleet or snow to the chamber 1. When the cover 11 is closed the productsof combustion pass away from the chamber 1 through the hole 1, chamber 2and flue 10 and heat said chamber i .2. The chamber '2 being tapered hasa tendency to retain the" heating medium therein and the curved formofsa id chamber also has the samevtendency, Heat is radiated from thechamber 2am raises the temperature of the water in which theheater issubmerged partially, The curved formof the chamber 2 also contributes tocompactas sembly of the devices and renders the location of the heaterin the tank more stable, The burner 3 may be removed, cleaned andreplaced or substituted by another as desired;

Whenever liquid fuel maynot be available, the burner 3 and pipe 7 may beremoved and ber of a burner loosel mounted Within said combustionchamber, a removable cover on the open end of said chamben'an airconduit hooked 'over one Wall of-saidchamber with its upperend outsideof and downwardly opening relativeto said chamber, said conduit passingthrough "said cover and having w its-lower end opening above and spacedfrom said burner, a fuel tank carried by the upper end of said conduitand a valve-controlled fuelpipe leading from said tank through saidcover and havingits lower end intersecting I saidconduit to dischargeaxially above said burner.
